390401-03-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 390401-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,0,4,0 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 390401-03:
(8*3)+(7*9)+(6*0)+(5*4)+(4*0)+(3*1)+(2*0)+(1*3)=113
113 % 10 = 3
So 390401-03-3 is a valid CAS Registry Number.
